Product Name: Air Flow Velocity Digital Anemometer, Handheld Wind Speed Meter Weight: 50-100g Waterproof: Waterproof Noctilucence: With Noctilucence Shakeproof: Shakeproof Anti-jamming: Anti-jamming Pressure Resistance: Without Pressure Resistance Connection Type: Wire Detection Method: Non-contact Display: Digital Application: Anemometer Trademark: OEM Transport Package: Gift Box Specification: 40x18x105mm Origin: Changzhou, Jiangsu HS Code: 9015800090 Product Description This product is a portable multi-functional anemometer, and it is suitable for measuring temperature, humidity, wind chill, dew point, wind speed, barometric pressure, altitude and illumination.Because the measurement of altitude is influenced by barometric pressure and temperature, so the altitude values measured in different seasons and different climates are different, but in the same day and condition that, barometric pressure and temperature slightly vary, the altitude reading is, stable, so it can be used for measuring the altitude difference.1. Air Velocity & Temperature Measurement;2. Max/Average/Current air velocity measurement;3. ºC/ºF Temperature unit selection;4. Five units of air velocity:M/s, Km/h, ft/min, Knots, mph5. Beaufort scale;6. Backlight display;7. Manual/Auto power shut off;8. Wind chill indication;9. Low battery indication.
